Organic semiconductors have attracted extensive attention due to their excellent optical and electronic properties. Here, we present an experimental and theoretical study of Brunel…
Two-XUV-photon double ionization of Neon studied at the Extreme Light Infrastructure (ELI-ALPS)
I. Orfanos, E. Skantzakis, A. Nayak +12
Two XUV-photon double ionization of Ne, induced by an intense few-pulse attosecond train with a ~ 4 fs envelope duration is investigated experimentally and theoretically. The exper…
Spatio-temporal sampling of near-petahertz vortex fields
Johannes Blöchl, Johannes Schötz, Ancyline Maliakkal +8
Measuring the field of visible light with high spatial resolution has been challenging, as many established methods only detect a focus-averaged signal. Here, we introduce a near-f…
